Stack of four, 30-second images @ ƒ/4, ISO 3200. Levels and RAW to JPEG in Aperture, stacking in WinImages, tracking with Astrotrac. Clouds were everywhere, and the longest exposures between them I managed to get were 30 seconds. I can tell the camera is acting differently with the Hα mod, more sensitive, but it's difficult to try to compare a 30-second exposure with a three minute one. Weather service says clouds for the next week or so.
